The Korean electronics giant's video, published Friday, gives a starring role to the number 5 in the video then concludes with the words "the next Galaxy." That broad a hint doesn't leave much to the imagination, though unlike many teaser videos, the phone itself doesn't make an appearance even in silhouetted form.

By showing a boy on a waterslide with the words "Wet5" overlaid, the video does suggest that one rumored feature -- that the Galaxy S5 will be waterproof -- has some truth. But all will be revealed in good time next week at Mobile World Congress in Barcelona.
